QSFP-40G-ER4=

Overview Of QSFP-40G-ER4=

The Cisco QSFP-40G-ER4= is a high-performance 40G base transceiver module designed to meet the demanding requirements of modern networking infrastructures. It supports a data rate of up to 40 Gbps, enabling high-speed data transmission for bandwidth-intensive applications. With its ER4 (Extended Reach 4) designation, this transceiver module is capable of reaching distances of up to 40 kilometers (24.85 miles) over single-mode fiber (SMF), making it suitable for long-haul connections. The Cisco QSFP-40G-ER4= module uses the Quad Small Form-Factor Pluggable (QSFP) form factor, ensuring compatibility with QSFP ports on Cisco switches and routers, as well as other networking equipment that supports QSFP interfaces. It employs four wavelengths (1271 nm, 1291 nm, 1311 nm, and 1331 nm) for transmitting and receiving data signals, maximizing bandwidth utilization and ensuring reliable communication over long distances. Designed for hot-swappable functionality, the module can be inserted or removed from compatible QSFP ports without disrupting network operation, providing flexibility and ease of maintenance.
